b7923dfd8c update PostgreSQL configuration in deployment files (#365)
- Change PostgreSQL volume mount from /var/lib/postgresql/data to /var/lib/postgresql
  This allows PostgreSQL to manage the data directory structure internally

- Add PostgreSQL version configuration variable to all docker-compose files:
  * POSTGRES_VERSION for deployment/nginx
  * APPSEC_POSTGRES_VERSION for all deployment/docker-compose variants

- Update PostgreSQL image tag to use version variable (set to version 18)
  Changed from 'postgres' to 'postgres:' or 'postgres:'

- Add PostgreSQL version variable to all .env files with default value of 18

[open-appsec](https://www.openappsec.io) (openappsec.io) builds on machine learning to provide preemptive web app & API threat protection against OWASP-Top-10 and zero-day attacks. It can be deployed as an add-on to Linux, Docker or K8s deployments, on NGINX, Kong, APISIX, or Envoy.
The open-appsec engine learns how users normally interact with your web application. It then uses this information to automatically detect requests that fall outside of normal operations, and conducts further analysis to decide whether the request is malicious or not.
